Niels Bohr Atom Theory

Lindsey: I am Lindsey McClure, reporting live to you from the WNTG news station.
I’m here with Niels Bohr, a physicist from Denmark born in 1885.
So, how are you? Tyler: Thank you for having me today. I am
doing exceptionally fine today and am glad to be hear on behalf of all my fellow colleges
to present to you my theory about the BOHR model.
Lindsey: so, what was your school life? Tyler: I was a trouble child that was always
up to no good. I procrastinated on everything, and did not do my projects especially the
essays. But that all quickly changed when I realized it would not go over well.
So who was your chemistry teacher? Lindsey: Mrs. Kennedy
Tyler: You mean she is still around? Lindsey: Gosh, she’s old…
Lindsey: I can see that actually see you as a troublemaker. You just seem like you are
that type of person to do that. Would you mind tell us, where did you attend college?
Tyler: I graduated from the UK at the University of Cambridge, the Victoria University of Manchester,
and University of Copenhagen in 1911 and 11 years later won the Noble peace prize in 1922.
Lindsey: Don’t get such a big head about that…
Wait- if you were born in the 1800s. How do you look so young?
Tyler: Cryogenic freezing. It was cold and I think I even have a little freezer burn
on my toes still. Lindsey: That must have been wonderful to
just wake up in the 21st century, without having to wait all those years.
Tyler: you guys sure are far behind what we expected you guys to be at we thought you
would have flying cars robot butlers and everything would be done for you. You guy are not even
got a single building on the moon. O and don’t even get me started on your economy and what
you have done to the environment Lindsey: let’s not get into that. Moving
on, if I remember correctly, your theory about atoms was originally based on Millikan’s
theory? Tyler: no actually it was based off of Rutherford’s
theory. He mainly got it incorrect because he thought that the electrons were still
Lindsey: I am sorry my sources were momentarily incorrect. The signal got mixed up with the
foot ball game they said Millikan got a touch down and I miss understood them. Did you make
a model of your theory? Tyler: yes I did It was called the Bohr model
after me but it is also called the planetary model because I thought that the electrons
orbited around the core in a constant motion. O and I figured that you guys would have at
least fixed that you guys are really far behind Lindsey: you’re…a very honest person,
aren’t you? How do you feel about being disproved? It was only, what, about 10 times?
Tyler: I try to be and hey if you don’t say your feeling you would be stuck in a boring
class. It’s not the best of feelings to be disproved but I am glad that I was disproved
to make science more accurate Lindsey: Very true. So, what was it like to
have studied under Rutherford and be there with him while he practiced his own atomic
theory? Tyler: I learned a lot and got a great experience.
Our entire class did I believe. He fired Helium nuclei at a piece of gold foil which was only
a few atoms thick. When atoms were fired at the foil, only a few actually stuck to it.
About 1 in 10,000. The others either bounced off or passed through.
Lindsey: I’m sure that the results was fascinating, yet probably anticlimactic. So, do you think
you could tell a little more about your modle? Tyler: Yes I could
1. The electrons can only travel in special orbits: at a certain distinct set of distances
from the nucleus with specific energies. 2. The electrons do not continuously lose
energy as they travel. They can only gain and lose energy by jumping from one allowed
orbit to another, absorbing or emitting electromagnetic radiation.
Lindsey: that a lot to take in Tyler: not for the time I took
Lindsey: Well that all the time we have so hope you have a good sleep. Back into the
freezer with you, Mr. Bohr. We’ll see you next time on WNTG.
